Title: Light beam path testing method
Inventor: MIKAWA IZUMI
IPC: G01M11/00
Filed: 1990-05-15
Abstract: PURPOSE:To obtain this testing method which does not depend upon the number of distributions by using ports of 1:n distribution components other than an incidence port and projection ports for testing and making signal light and abnormal wavelength monitor light incident, and projecting back scattered light from respective optical fibers from the ports. CONSTITUTION:The ports which are not used usually are used as ports 21 for testing. The test monitoring light from a light pulse tester 12 is made incident on the test ports 21 of the 1:n light distribution components 5 and the back scattered light which is generated by trailing start part optical fibers 4 is projected from the testing ports 21 and light-received by the light pulse tester 12. Consequently, the start part optical fibers 4 connected to the respective 1:n light distribution components 5 are tested and controlled by individual light- reception and test monitoring which does not depend upon the number of distributions is available.

Title: Three-dimensional shape measuring instrument
Inventor: HIRUKAWA HIDEO
IPC: G01B11/24
Filed: 1992-05-15
Abstract: PURPOSE:To correct the straightness of a stage and measure the shape of an object to be measured with high accuracy by detecting the difference in height between the object and a plane mirror for reference and inclination of the plane mirror for reference with an optical probe. CONSTITUTION:The inclination of a plane mirror 3 for reference can be found from the position of a beam detected by means of a position detector (PSD), because the position of the light transmitted through the half mirror 62c of an optical probe 6 changes. The part of the light reflected by the mirror 62c interferes with the light from a mirror 63a of a measuring optical path after advancing an optical path from a PSD 65 to a photodiode 71 through the mirror 62c. Since the photodiode 71 outputs the variation of the height difference between an object 4 to be measured and the mirror 3 as interference signals, the height difference is found by integrating the interference signals. Since the movement of a movable stage section 2 is measured with a laser length measuring instrument 5, a controller 8 finds the surface shape of the object 4 by combining the position of the section 2 and the height difference obtained from the probe 6.

Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To easily realize the change of a focal distance and focusing by providing a guiding means so that the 1st lens unit may draw a locus obtained by connecting plural different loci in an optical path with respect to the 2nd lens unit in the optical path. SOLUTION: When a zoom ring is rotated by 30 deg. from a state where the focus of a lens is set to ∞ in the case of WIDE, the magnification of a photographing lens system does not change during the state shown by an arrow D, and the focusing is performed by the rotation of the zoom ring while keeping the WIDE state. In the case of switching to a normal(NOM) mode, a lens position where the focus is set to ∞ in a NOM state is obtained when the zoom ring is rotated to a position showing 90 deg.. When the zoom ring is rotated further from this state, the focusing is performed while keeping the NOM state till attaining 135 deg. similarly to the WIDE state. When the zoom ring is similarly rotated by 180 deg. in the case of TELE, the focus is set to ∞ in the TELE state. The adjustment of magnification and the focusing are performed only by rotating the single zoom ring.
